`1\l[ElCHANISM FOR TRANSMITTING IVIO'IION.`

T0 ZZ/whom it may concern:

Be it known that I, HENRY F. Moenia, a citizen of the United States, and` a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mechanisin for TransmittingMotion, of which the following is a specification. i

This invention relates to a device which is used to move the horizontal members of a grate, at determined"intervals, and the object of the invention is to obtain a device which, by automatically actuating said `movable members, will automatically` supply `coalto a grate, will automatically stoke said little care `and attention to operate it; which does not require a person to be particularly skilled in mechanics to use and care for it;

which is durable; not liable to break or `get by means of connections e.

out of order; and sightly inappearance.`

` In the drawings accompanyingand forming a part hereof Figure 1 is a front elevation of a boilerwfront and of mechanism embodying this invention y attached thereto.

Fig.2 is a side elevation of the operating mechanism whichis illustrated in Fig. 1,

`and showing the upper `end of a grate mechanism actuated therebygfFig.` 3 is a side elevation of a` camv forming an element in` the operating mechanismlof the device. Fig.

4t is a front elevationofthe lower end of a` lever which forms an element in said oper` ating mechanism. Fig. 5 is a side elevation saidsliding memberand Fig. 8 is a i'ront` elevation thereof. Fig. l9 is a sideelevation of an additional sliding member, and of a hook which is pivoted thereon, and Fig. 10 is an elevation of the sliding member which is illustrated in Fig. 9.

Fig. 13 is a front elevation of a boiler front and of a modification of the mechanism embodying this invention. n elevation of the modification which is illustrated in Fig. 13; and Fig.` 15 is a side elevation of said modication, viewed at an angle of 180o from Fig. 14C.

F is a rocking shaft which is journaled in bearings a on supporting members A.

i (l is a link which is pivotall;7 attachedat one of its ends tomovable member D and Fig.` 14:` is aside at the other end to one of the narms of` bell i crank G. Members D are `provided with `slots d,and d are bolts in slots d. Horizontal movement `of members E is obtained The advanced position of the horizontal movable member E is indicated by the broken lines E in Fig. 2.

The inechanismembodying this invention `is designed to automatically obtain, at regular, and not too frequent, intervals, a `rocky ing of the shaft F (said shaft F forming an element in said mechanism).

` H is a guide secured to the front of the boiler to which the device is attached; I, I are the separable `partsof a slidinghead which is movably mounted in said guide Hg z' is an abutment onpart I of said head, and z" is a pivoted hook on `part I of the head.

Hook engages with the abutment 21 to join said parts I and I together. i

J `is a rotating crank shaft `journaled in bearings J.

p operative position.)

lever M and is pivotally attached to the' End m to one arm ofbell crank 'G .and .to part I of the two part head.

M is a lever pivoted at m on bracket Y.

N is a cam on shaft mand N is a ratchet wheel on said shaft.

O is a dog or pawl.

P is a bell crank attached to bracket fg.

by jpivotp.' Paw-l O is'` ivotally mounted on bell crank P. Said bell) crank P is actuated in one rdirection by abutment p wheel y, and in the other direction by the weight of 4.the horizontal arm of said bell crank.

The lower end of connection K moves up Aand down once fto each revolution of crank shaft J, and moves .part I of the two part head in guide H. 'Cam Wheel N is attached to shaft 'n to 1rotate therewith, and said shaft is moved in a step bystep movement by Apawl "O engaging with Vthe ratchet teeth of wheely N, as said 'bell crank P is` and '2, the pawl "Olgive's one impulse tov Wheel N, shaft n and wheel vcam N, on Additional impulses to said wheel, shaft and cam w'heel are given by placing kadditional abutments on the side of wheely j, if desired. Connection f-L is moved upward by the upward movement of part 4I ofthe two part head, g and said part I is `vmoved upwardby part I of saidhead when. the hookz" thereon 1s in engagement with the Yprojection z' on part I. I" isa spring which yieldingly holds the: hook z" out of engagement with abutment z'. l Hook c" isl forced into position to engage` with projection or abutment i by the lower;

end oflever M, when said lever is moved by camwh'eel N, (provided saidflower end is in m" is the lower end of `body part of lever M by pivot m. can be turned on its pivot so as not to engage with hook z", (see broken lines in. Fig. 4L), and when it is so turned the movement of head I -does not movehead I. v When'said end m is in position vto force hook z" against projection' or abutment i it is rigidly-maintained in place by butterfly nut M. a .pluralityfof 4these devices, and of grates,

are installed -under a plurality of boilers, or' in. the case, of .a very large boiler under a,

lsingle one,` the crank shaft J Imay be eX- tended .to operate/the horizontally .movable members of all said grates, which'does away with the necessity lof more than one of said crank shafts. `Where a plurality of hori-l on gear Where of the fire is desi-red Lthe 'automatic operation of the device is cut out by turning the end m out of operative position, as hereinbefore described. i

In the modification which is illustrated in Figs.. 13, l'and l5, the crank shaft J is .provided with the crank j, and at its opposite end is also provided witha crank Q. Crank Q is provided with roller g. Crank Q, performs the functions of projection or abutment p, (illustrated in Figs. l and 2).

P is a pivotally mounted lever which is provided with the pawl or dog O".` Ratchet wheel N is rotated in a step by step movement 'by means of pawl 0, lever P and crank Q, on the revolutionof the shaft J, in the same manner as said ratchet wheel is rotated in the hereinbe'fore ldescribed construction by means of pawl O'. lIn Ythis ,modification the about to be described construction is substituted for lever M" and its appurtenances, to automatically obtain lthe engagement at stated intervals of the hook z" with projection or abutment z'. I-Iook '11 is provided with vthe arm which rests on the pivoted lever R. Said lever Ris pivoted on one side'of guide I`I,'.by .pivot r. Arm S is pivoted 'to bracket y by pivot S, so, as to rest on the'cam wheel N and to be actuated by connection T. t is a spring which is interposed between connection T and arm .S,'to obtain what may be termed a take .up =mo tion; that is, permitting thearm S to move on its'pivot more than the arm or lever R is .allowed or required to move on its pivot. U, Fig., lll, is a'spring, one end of which abuts against 'the vbracket u and the other end lagainst the arm or lever P, yieldingly holding said lever P. in' its determined initial position. u" is a rod or bolt extending throughbracket w and v"spring U, land pivotally attached to arm P; and'said rod lor bolt is Xprovided with'the Atake up nutsu.

V are broken lines indicating'a portion of a lever which may be insertedin `a pocket or socket which is gprovided therefor in arm V. Lever V is used to manually operate r.the shaft F to actuate horizontal` members D and E. A I claim f f l. l 'In mechanism for :transmitting motion 'to a horizontally-movable grate member, 'the combination of saidhorivzontal member,

a crank shaft, means torotate saidfc'rank shaft, a head, a connection between said crank shaft and said head, an additional head, a rigid hook on said first named head and a movable hook on said additional head, said movable hook adaptedto co-act with said rigid hook, means to yeldingly hold said hooks out of engagement, a cam, a lever, said lever adapted to force said movable hook into engagement with said rigid hook when actuated by said cam, and a connection between said additional head and said horizontallly movable grate member.
